ている。（実開平１−１６６４１９号公報）2. Description of the Related Art Conventionally, in this type of electric connection box, a bus bar formed by punching a conductive metal plate is used as an internal circuit. However, if the internal circuit is constituted only by the bus bar, it is not possible to easily cope with a change in the design of the internal circuit. Therefore, as shown in FIGS. There has been proposed a circuit using the terminal T as a load-side circuit in which design changes are likely to occur, and using a bus bar B as a power-supply-side circuit.

業工程が増加する問題がある。When the power-supply-side circuit shown in FIG. 5 is constituted by a bus bar and the load-side circuit is constituted by an electric wire and a press-connecting terminal, a circuit having two kinds of different constitutions is constituted by one circuit. Since it must be provided inside the electric connection box, there is a problem that the internal structure of the electric connection box becomes complicated, many types of components are required, and the number of working steps is increased due to different mounting manners.

Further, when the power supply circuit is shared by other types of vehicles, the power supply circuit often needs to be changed. In such a case, it is necessary to reconfigure the bus bar. Therefore, even if only the load side circuit is constituted by the electric wires and the press contact terminals, the problem that occurs when the circuit is constituted by the conventional bus bar cannot be solved.

Are arranged and divided into layers. However, since the load side circuit occupies 90% of the entire circuit, electric wires are densely arranged on the lower layer side and wiring becomes very complicated. Therefore, there is a problem in that when the electric wires are to be wired also on the upper layer side, the tabs of the bus bar are in the way and cannot be easily wired.

Electrical junction boxes must be provided separately. Also, since only one layer of the electric wire w is arranged, it is not possible to cope with the case where the number of circuits is large, and furthermore, the electric wire and the pressure contact terminal are connected when the upper case and the lower case are assembled. There is a problem that an internal circuit connecting the pressure contact terminal and the pressure contact terminal cannot be formed in advance.

Both a large current circuit and a small current circuit of an electric junction box are composed of electric wires and press contact terminals. It is an object of the present invention to provide an electric connection box in which electric wires for electric current are arranged in a well-balanced manner inside a case of the electric connection box, so that the electric connection box can be made thin.

る。In order to achieve the above object, the electric junction box of the present invention uses a thick wire for a large current circuit and a thin wire for a small current circuit. The electric wires and the thin electric wires are mixed and wired along an insulating plate housed inside the electric connection box, and press-contact the press-connecting terminals at required positions to form an internal circuit.

果、電気接続箱の薄型化を図ることができる。As described above, when a large current circuit such as a power supply circuit is also made of a thick electric wire, the degree of freedom in wiring is increased, the size of the electric junction box can be suppressed, and the design can be easily changed. Also, in the internal circuit of a large electrical junction box, 90% of the entire circuit is usually a small current circuit. Therefore, if the thin wires of the small current circuit and the thick wires of the large current circuit are arranged in layers, Wires are concentrated on the small current circuit side, making it difficult to wire.However, if thick wires for large current circuits and thin wires for small current circuits are mixed and wired in the same layer, the wires will be Can be distributed to each layer in a well-balanced manner, and as a result, the electrical junction box can be made thinner.

流を通電しても問題はない。A single core wire is preferably used for both the thick electric wire and the thin electric wire. The thick electric wire for a large current circuit has a core wire having a sectional area equivalent to 1.25 mm2 or more, and the thin electric wire for a small current circuit. The one whose core wire has a sectional area of less than 1.25 mm2 is used. In general, a wire having a core wire made of a stranded wire is used for a wire through which a large current flows, but this stranded wire has a problem that a contact area cannot be kept constant at the time of crimping with a press contact terminal. When a thick electric wire having a single core wire is used, the contact area with the press contact terminal can be kept constant, and there is no problem even when a large current is supplied.

Can be matched. Similarly, when a small electric wire having a small core wire is used in the load-side circuit through which a small current flows, the amount of current flowing through the electric wire can be set to an appropriate value on the load side.

Thereafter, the upper case 1 and the lower case 2 are assembled, and the input / output terminal portions 6c to 8c of the press contact terminals 6 to 8 are inserted into the terminal accommodating chambers formed in each case. Further, retrofit parts such as a fuse and a connector are assembled to the upper case 1 and the lower case 2 to assemble the electric connection box.

気接続箱の薄型化を図ることができる。As is apparent from the above description, in the electric junction box according to the present invention, the large current circuit of the internal circuit is constituted by a thick electric wire, and the small current circuit is constituted by a thin electric wire. It can easily respond to changes. In addition, since the thick electric wires and the thin electric wires are mixed in the same layer so that the wiring can be performed, the electric wires can be distributed to each layer in a well-balanced manner. Therefore, it is possible to suppress an increase in the thickness of the electrical junction box, as well as to increase the thickness of the electrical junction box, thereby making the electrical junction box thinner.
